Description

Transmission line maintenance ground wire coupler

technical field

The invention relates to an electric power installation tool, that is, a ground wire coupler for power transmission line maintenance.

Background technique

The 220kV grounding wire needs to be dropped for power outage inspection and maintenance of the transmission line, and the operator should clamp the wiring clamp to the grounding wire. Since the ground wire is on the outer corner side of the corner strain tower, and there is still a distance from the pole tower, the operator should throw out the clamp and hang it on the ground wire. Because the ground wire is easy to swing, when the wind force exceeds level 3, it is difficult for the operators on the tower to successfully hang it at one time. It takes about 15 minutes for each phase wire to hang the ground wire, and it takes about 45 minutes for the three-phase wire to hang the ground wire. , reducing work efficiency and increasing power outage time.

Contents of the invention

The purpose of the present invention is to provide a ground wire coupler for maintenance of power transmission lines that can accurately clamp the wire clip on the ground wire without throwing, is easy to operate, saves time, and greatly shortens power failure time.

The above purpose is achieved by the following technical solutions: develop a power transmission line maintenance ground wire coupler, including a clamp that matches the ground wire, and is characterized in that a joint is installed on the clamp, and the joint has a connecting plate , the lower part of the connecting plate is connected with the clamp, the upper part of the connecting plate is provided with a casing, the middle and upper part of the casing is provided with a gap, one side of the pipe wall is provided with a side port, the side port extends to the middle of the casing, and is connected with the casing The gaps on the wall are connected, and the joint is equipped with a slender insulating rod. The front end of the insulating rod has a section of insertion rod that matches the sleeve. One side of the insertion rod has a protrusion that can slide in the side opening and turn into the gap. . When in use, the insertion rod at the front end of the insulating rod is inserted into the casing, and the protruding column is turned into the gap through the side opening to lock the clamp, and then the insulating rod is pushed to forcibly connect the clamp to the ground wire.

The beneficial effect of the invention is that maintenance personnel can complete the installation of ground wires without throwing wire clips, the operation time is shortened by 70-80%, and it has the advantages of simple structure, low cost, and portability, and is expected to become a necessary equipment for maintenance operations. tool.

Detailed ways

The general idea of the present invention is to install the clamp to the ground through an insulating rod. Only an example is given below:

Embodiment: As shown in Fig. 1, Fig. 2 and Fig. 3, this kind of power transmission line overhaul ground wire coupler is to install a joint 2 on the line clip 1. It can be seen from Fig. 4, Fig. 5 and Fig. 6 that the main body of the joint 2 is A connecting plate 3, the lower part of the connecting plate 3 is connected with a clamp handle of the wire clamp 1 through a bolt 4, a casing 5 is arranged on the connecting plate 3, a notch 7 is arranged in the middle of the pipe wall in the middle of the casing 5, and a gap 7 is arranged in the middle of the pipe wall. A side port 6 is provided on the side, and the side port 6 extends to the middle of the casing 5 and is bent upwards and communicates with the notch 7 on the wall of the casing. A slender insulating rod 8 can be seen in conjunction with FIG. 7 . The front end of the insulating rod 8 has a section of inserting rod 9 matched with the bushing 5 , and one side of the inserting rod 9 has a protruding post 10 . During use, the inserting rod 9 at the front end of the insulating rod is inserted into the casing 5, and the protruding column is transferred to the gap 7 through the side opening 6 to fix the clamp 1 on the front end of the insulating rod 8. The maintenance personnel climb to the proper position of the pole tower, and then the insulating rod can be pushed to clamp the line clamp 1 on the ground wire 11. Twist insulating rod 8 again subsequently, take out insulating rod and get final product. After the operation is completed, the insulation rod can be plugged again, and the wire clamp can be pulled down.

According to the test, it takes only 3-5 minutes to install a phase ground wire with this device, which is 10-12 minutes less than the original one. Moreover, the difficulty of operation and the tension of the operator are significantly reduced, and the labor intensity is greatly reduced, the work efficiency is significantly improved, and the power outage time is greatly shortened, which is well received by users in the experimental area.
